Hello? @campbell_st

campbell_st · Answer

6 isn't the GCF of 16 and 40... 

the factors of 16 are   1, 2, 4, 8, 16
                      40         1, 2, 4, 5, 8, 10, 20, 40

what is the largest common factor.... of 16 and 40...?

ok... now look at 

$$x^5 = x \times x \times x \times x \times x$$

and 

$$x^4 = x \times x \times x \times x $$

what is the largest number of x's that are common to both x^5 and x^4
